noonon n'o i Application filed August so, 1930. seria n tvsaasa This invention relates to door stops or door checks and has for an object the provision of a simple and cheaply manufactured device, which when positioned for use, will per- .mit of the rapid closing of a door throughout the major portion of its movement, and thus prevent the passage of flies and other insects, but which will effectually check the door just prior to its contact with the door frame,

so that the door will be fully closed without noise or jar.

Vihth the above and other ob ects in view,

the invention further includes the following novel features and details of construction,

to be hereinafter more fully described, illustratedin the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a fragmentary elevation illustrating the invention in use.

Figure 2 is a section on the line 2-2 Figure 1.

Figure 3 door open.

Figure at is an enlarged vertical sectional view through the door check or retarder. I

Figure 5 is an elevation partly in section showing a slightly different formof the invention. a

Figure 6 is a vertical sectional view of another form; V

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the invention is shown as is a similar view showing the i applied to a screen door 10, the frame of which is indicated at 11. While the invention 1s shown in connection wlth a screen door,

obviously it may be applied to other doors, or to other hinged closures.

The reference character 12indicates a cuplike receptacle or holder which is designed for attachment to the door frame 11,'and for this purpose'is provided with openings for the passage of screws 13, or-equivalent fastening devices. Extending from the outer edge of the receptacle 12 is an inflatable member 14. This-member is formed of rubber of asuitable thickness and is arrangedvin the path of an arm 15. This arm is rigid and is secured to the door as shown at 16 I and free end is provided with a ball or knob 17 to engage the inflatable member 14.

, *Whenthe door is moved "to 'a closed iposi tion under the action of the spring 18,-iit will quicklyv close so as to prevent-the passage of flies and other insects through the doorway. The arm.15 and theiinflatable memberal i are 1 so positioned that the 'ball. at the end of the arm 15 will engagethe inflatableimember'l l just prior-to contact of'the'door with the i 7 door 'framef Closing movement of'the door may thus be checked or retarded at this point, and as the remainingmovement 20f the door willbe retarded by thefimember 14, the door will jointly engage the frame and eliminate as noise and jar. i 3' I The member leis provided with an air escape *OPen'lDg 19 which is 'contr'o'lled by a valve member '20 and this member' is weighted as shown'at'izl. That portion of th e mem- 7 ber 14 "within theireceptacle 12 is reinforced and stiffened, and for this purpose, the-form of the iinvention shown in Figure 4 is provided wlith acup-likereinforoingmember 22.

This member is preferably formed of rela- 76 ure 6, the construction issubstantially the same except that the member 14c is thickened as shown at 27, and a screw 28 is threadedly.

engaged with this thickened portion.

In Figure5, the receptacle 12 is, provided around its edge with an inwardly extending fiange30 which detachably engages an annular shoulder 31 provided upon an inflatable member 32.

The invention is susceptible of various changes in its form, proportions and minor details of construction and'the right is here in reserved to make such changes as properly fall within the scopeof the appended claims.

Having claimed is described the invention what is 1. A door check including a cup-like receptacle adapted vto be secured tothe door frame and having aninwardly projecting socket formed centrally of thebottom there* of, a hollow inflatable member having a re-- inforced portion partly receivedby the receptacle, and a headed bolt passed through said socket and secured to said reinforced portion of the inflatable member tohold the 10 latter associated with the receptacle,

2. A door check including. a cup-like re- 'ceptacle adapted to be secured to the doorv frame, a hollowrinfiatable member having a reinforced portion received by the receptacle, c

15 and means including said reinforced portion of said member for connecting the latterto the bottom'of the receptacle.

7 3 A door check including a cup-like receptacle adapted to be secured to the door 20 frame, a hollow inflatable member partly received by the receptacle, a cup-like reinforc ing member arranged within the receptacle and Vulcanized to the adjacent portion of the inflatable member; and means including said 25 reinforcing memberfor connectingthe in flatable member to the bottom of thecrecepta-I ole.- v r I v is 4:. A door check including a cupelike receptacle having an inwardly projectingsocket formed centrallyof the bottom thereof; a 7 hollow inflatable member partly received by V the receptacle, a cup-like rubber reinforcing memberarranged within the receptacle and vulcanized to the adjacent portion of 3 the inflatable member," and a headed bolt passedthrough the socket zindthreadedly connected withthe reinforcing member;
